Homework Help: HW prob mass conservation

  1. Sep 24, 2005 #1
    so i got this HW prob, and i dont know exactly where to start,

    Oil flows steadily in a thin layer down an inclined plane. The velocity profile is

    u = [(density)(g)(sin theta) / Mu] [(hy - (0.5)y^2]

    express the mass flow rate per unit width in terms of density, Mu, g, theta, and h

    no diagram is given.

    If you're given a velocity profile, that's the function of velocity as you go away from the base. You're going to need to integrate to get a solution.

    I'm going to move this to homework help.
